search for: bgroup

Dear R user community I wanted to use "bgroup" for plotting a math formula with a big "{" on the left, and nothing on the right. i used text( 10, 10, pos=4, cex=1.8, expression(F(x) == bgroup("{", x, "")), ...) on a 40 x 20 plot. surprisingly, bgroup sets "Phi(xi) = { xi" i.e. replaces alphabet...

Dear list, I read in ?plotmath that I can use bgroup to draw scalable delimiters such as [ ] and ( ). The same technique fails with < > however, and I cannot find a workaround, grid.text(expression(bgroup("<",atop(x,y),">"))) Error in bgroup("<", atop(x, y), ">") : invalid group delimiter R...

Let me summarize the bug reported by Ulf Martin on R-help with the same subject line. The code plot(1:10) text(1, 9, expression(F == bgroup("{", x, ""))) results in greek letters, which is not expected here. That happens if the user tries to set only a left delimeter, the same with: text(2, 8, expression(F == bgroup("{", x, "."))) or text(3, 7, expression(F == bgroup(".", x, &...

...Windows XP machines see files as read-only. Windows 7 works fine on the same files. The Sun has a non-Samba CIFS implementation but it's non-intuitive to set up so I haven't tried it.

ComRades, How do you put a superscript on a scalable delimiter? I want to put 'b' as the power of the expression in the following plot: t <- 1:25 K <- 0.2 y <- ((1-exp(-K*t))/(1-exp(-K*t)*exp(K)))^3 plot(t,y,"l",main="K=0.2, b=3") text(15,5,expression(bgroup("(",frac(1-e^-Kt,1-e^-Kt*e^K),")"))) Plotmath examples in demo(plotmath) do not include this. I've tried a few things to no avail and I did an RSiteSearch("superscript delimiter") with zero results. Thx Rub?n _____________________________________________________...

Hi All, I am trying to lable the y-axis on my scatterplot with the following: "Soil moisture content (m3m-3)" I am using the following coding for plotting the graph: plot(soilmoisture~gradientlevel, xlab="Levels of droughting gradient", ylab="Soil moisture content (m3m-3)", bty="l", font.main="2", pch=16, las=1, cex.lab="1.13") I have

Dears, do you know whether it is possible to include any square parantheses (brackets) in an expression to use it as an axis label? e.g. I would like to have a label like (with the sub and superscripts correct): "speed [m s^-1]" I know how to combine an expression with text via paste, but as I run soimething like: a='m*s^{-1}' plot(1:10,main=parse(text=a)) I found now way

I want to shade the area under the curve of the standard normal density. Specifically color to the left of -2 and on. How might i go about doing this?

I hope to use the plotmath facility to print titles that mix math and values of R variables. The help for "plotmath" has an example, which after repeated reading, I find baffling. Likewise, I have read the help file for "substitute" (wqhich seems to be needed) without ever understanding what it does, other than being used in some magic incantations. I would like to do

Hi everyone, This series of patches of dm-ioband now includes "The bio tracking mechanism," which has been posted individually to this mailing list. This makes it easy for anybody to control the I/O bandwidth even when the I/O is one of delayed-write requests. Have fun! This series of patches consists of two parts: 1. dm-ioband Dm-ioband is an I/O bandwidth controller implemented
